What you do next depends on what Windows operating system you're using:

In Windows 7, click System and Security.

In Windows Vista, choose System and Maintenance.

In Windows XP, click Performance and Maintenance.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.
